Bike smoking + drinking oil..

You can pick up a decent engine on Ebay for £350-400. Certainly much much cheaper than having the existing one fixed.

Even if it's *just* those valve stem seals or piston rings?

How much is my fooked engine worth?? it still works .. not sure how long it'll last for though

You are a 1 man wrecking machine

I wouldn't mind the KTM to play with though

Probly is all down to wheelying. Look what happened to my bike. Because of to many wheelies that burnt the oil in the engine. Same way i did mine. Sound likes youve got the cheaper option though. just hope to god you've got nothing wrong with ure gearbox. thats the expensive part!

yea piston rings 99%. obscene amount of labour and even worse doing it yourself. New engine

Try some redex engine oil stop leak and sell it. lol worked like a champ with my pug 405

Redex?Thats probsbly what the previous owner did before unloading it.If its as bad as you say, I doubt if any botch job will stop it burning oil.You will have to fix it or flog it as is.

I doubt he did that very much mate he's a well known member of this forum and it was 99% my fault as I was doing wheelies???

I break everything I touch mate, I'm useless, completely useless.

p.s. thanks for the tips with the redex but I wouldn't do that to any one, as that's WELL out of order.. nearly as out of order as the bloke who tried to sell me a Cat B write off bike ( frame should have been crushed ) without telling me! (thank you HPI! )

Looks like I'm selling the quill can, gel seat, bodywork and hugger just to get some money up and will take it from there I guess.

Also I was told that if it only smokes at start up it's prob the valve stem seals rather than piston rings?? Apparantly piston rings will cause the bike to smoke ALL the time? Not just at start up.

OK first off, when does it smoke? Only at startup or all the time?

If it's just at startup then it could be the valve stem seal/s or guide/s, if it is, you may also notice a puff of smoke on gearchanges and on a shut throttle. Not too dear to fix.

If all the time, then it's most likely bore/piston ring wear. Problems in this area aren't that dear to fix. Assuming you have no other suspicions of engine wear/damage, then a repair should be investigated first by doing a compression test, this will tell you which cylinder is worn. If there's knocking from the bottom end or excess vibration, usually on a shut throttle, then the engine will be dearer to fix than replace.

If there are no suspicions of other damage then oil starvation is not likely to be the cause, if it were an issue then the first area to suffer woud be the big ends.

In the circumstances you have described I think there is room for optimism, you haven't mentioned any other problems so your trouble is most likely one bore, perhaps broken rings, unless the engine is very high miles or perhaps has been run on unfiltered air for an extended period, then it's not likely to be both bores.

Wheelies: Oil starvation can be caused by pulling monstrous wheelies, but as mentioned above, the bores/rings aren't likely to be the first problem.

Get a compression test done first, that'll tell you where to go next.
